Optimal control of micro-grid autonomous hybrid power stations based on modeling of stochastic energy consumption

摘要

Micro-grid power system becomes today vital reality for many of energy applications including remote habitations areas, military bases, and retranslation and communication equipment and so on. One on the central problem during developments of such systems represents the pressing need to optimize a) the structural design of all facilities including renewable sources (solar), controllable sources (diesel-generator), electrical storage (batteries) and b) control of energy flows inside a system providing optimal efficiency and minimum of fossil fuel consumption. Present works provides the simulation modeling of entire micro-grid system having various parameters of all system components. The special accent was made on the simulation of electrical power consumption models, which was developed taking into account significantly stochastic behavior of energy demands. Simulation modeling was realized by the application of MATLAB/Simulink program software. Stochastic models of energy demands and solar energy possibilities were developed on the base of real data were registered during prolonged period of time in the Negev region of Israel.
